Man, this was such a good movie. I loved the characters, art, and sound. I was thinking I was in the movie. I watched this again recently, but did so back when it first came out. I really liked the story too, and felt like it was well told. There was no issues with animtion, sound, or anything beyond the scores.
Other than that, I really thought it was a good anime movie and was worth buying it so I can own it legally.
